You bought a model and you want to scale the model, for example.
You can work in the progamma vectric aspire in two ways.
Scale the entire model by selecting it and dragging the anchor on the corner.
Press and hold shift key.
The model is then scaled proportionally, in x, y, z (height width length).
However, if you only want to scale the height, use only: “Adjust height” (scale z height).
You can then see the original height, do not overdo it because the model may be out of proportion.
